 Simulation and evaluation of a process concept for the generation of synthetic fuel from CO2 and H2Daniel H. König, Nadine Baucks, Ralph-Uwe Dietrich and Antje Wörner Energy, 2015, vol. 91, issue C, 833-841 Abstract: Future aviation, shipping and heavy load transportation will continue to depend on energy carriers with a high energy density. The Power-to-Liquid technology is an approach to produce synthetic hydrocarbons, which fulfill this requirement. The proposed concept is based on H2 from electrolysis, which reacts with CO2 via the reverse water-gas shift reaction to syngas. Syngas is then synthesized to liquid hydrocarbons by Fischer-Tropsch synthesis. A downstream product separation and upgrading section allows the production of defined fractions for specific applications. A flowsheet process model is build and heat integration is conducted. The input capacity is set to 100 MWLHV of H2. A total amount of 1260 bbl/d liquid hydrocarbons (67.1 MWLHV) is generated. The carbon conversion and the Power-to-Liquid efficiency, which is defined as the fraction of the electrical energy chemically bound into liquid hydrocarbons, are identified as the parameters to evaluate the overall process performance. The Power-to-Liquid efficiency is found to be 43.3%. The carbon conversion rate of 73.7% indicates the exploiting of the introduced CO2.
